Brief Summary:
This is a prospective, observational, non-interventional patient registry study designed to document product safety and effectiveness outcomes for 10 years in patients treated with Cholbam, including those who have been using Cholbam for at least 30 days (existing users) and those who are first-time initiators of Cholbam.

Condition or disease Intervention/treatment
Bile Acid Synthesis Disorders Drug: Cholbam

Detailed Description:
No experimental intervention is involved. Patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of participants with worsening cholestasis [ Time Frame: 10 Years ]
    Worsening cholestasis will be identified by measuring direct total bilirubin concentration in blood and will be defined as a 25% increase from previous measurement if the total bilirubin is >1mg/dL.

  2. Number of participants with new-onset cholestasis [ Time Frame: 10 Years ]
    Patients with new-onset cholestasis will be identified by detecting abnormal direct bilirubin concentration >1mg/dL or direct bilirubin greater than 20% of the total bilirubin if total bilirubin is >5mg/dL.

  3. Number of participants with steatorrhea leading to poor growth [ Time Frame: 10 Years ]
    Steatorrhea leading to poor growth in children, which will be defined as a decrease in growth percentiles from the original percentile at enrollment to the registry study.

  4. Changes in serum levels of fat-soluble vitamins [ Time Frame: 10 Years ]
    Fat-soluble vitamin (A, D, E, K) deficiencies will be identified by comparing results from serum assays (Vitamin A: Retinol, Vitamin D: 250HD2 + 250HD3, Vitamin K: Serum Vitamin K, Vitamin E: Serum Vitamin E) for each vitamin with standard ranges.

  5. Neuropathic signs or symptoms related to fat-soluble vitamin deficiencies [ Time Frame: 10 Years ]
    Neuropathic signs or symptoms related to fat-soluble vitamin deficiencies (peripheral neuropathy, cerebellar ataxia) will be assessed by the Investigator.

  6. Number of participants with growth failure [ Time Frame: 10 Years ]
    Growth failure that the physician judges to be attributable to malabsorption.

  7. Death [ Time Frame: 10 Years ]
    AEs and SAEs leading to death will be recorded. The relatedness of death to Cholbam or disease progression will be recorded.

  8. Adverse effects on pregnancy, pregnancy outcomes, and infant status [ Time Frame: 10 Years ]
    Adverse effects on pregnancy, pregnancy outcomes, and infant status will be recorded.

  9. All Adverse Events (AEs) and Serious AEs (SAEs) [ Time Frame: 10 years ]
    All other AEs and SAEs will be collected.


Secondary Outcome Measures :
  1. Changes in Cholbam dosing regimens and reasons for any dose modifications or treatment discontinuations [ Time Frame: 10 years ]
  2. Changes from baseline in weight [ Time Frame: 10 years ]
    For patients aged 18 years of or less, these data will be converted into Z-scores based on the WHO growth standards for infants aged 0-2 years and the Centers for Disease Control and Prevention growth standards for children 2-20 years. Growth failure will be defined as a decrease in percentiles from the original percentile at entry point into the registry study.

  3. Changes from baseline in length/height [ Time Frame: 10 years ]
    For patients aged 18 years of or less, these data will be converted into Z-scores based on the WHO growth standards for infants aged 0-2 years and the Centers for Disease Control and Prevention growth standards for children 2-20 years. Some patients will be adult or will have achieved final height. Growth failure will be defined as a decrease in percentiles from the original percentile at entry point into the registry study.

  4. Changes from baseline in head circumference in infants [ Time Frame: 10 years ]
    For patients aged 18 years of or less, these data will be converted into Z-scores based on the WHO growth standards for infants aged 0-2 years and the Centers for Disease Control and Prevention growth standards for children 2-20 years. Growth failure will be defined as a decrease in percentiles from the original percentile at entry point into the registry study.

  5. Age-appropriate developmental milestones in infants [ Time Frame: 10 years ]
    Measured by WHO Motor Development Milestones

  6. Changes in prothrombin time (PT) [ Time Frame: 10 years ]
  7. Changes in international normalized ratio (INR) [ Time Frame: 10 years ]
  8. Changes in albumin [ Time Frame: 10 years ]
  9. Changes in bilirubin [ Time Frame: 10 years ]
  10. Changes in direct bilirubin [ Time Frame: 10 years ]
  11. Changes in alanine aminotransferase (ALT) [ Time Frame: 10 years ]
  12. Changes in aspartate aminotransferase (AST) [ Time Frame: 10 years ]
  13. Changes in gamma-glutamyl transferase (GGT) [ Time Frame: 10 years ]
  14. Changes in alkaline phosphatase [ Time Frame: 10 years ]
  15. Presence or absence of urinary bile acids and levels of bile acid intermediaries and urinary bile alcohol [ Time Frame: 10 years ]
  16. All indications for which Cholbam has been prescribed [ Time Frame: 10 years ]
    Description of all indications for which Cholbam has been prescribed
